I have recently bought a chinese copy of a Suzuki GN125 (with an engine which is a copy of the one found on a Honda GC125!!) . To improve smoothness, reduce engine stalls i am upgrading some chinese parts with better ones.

I already changed the chinese spark plug for a NGK one which improved a lot.
It idles great and i have had no engine stalls so far

Now my question: Would changing the Sheng Wey PZ26 carb to one for example made by Walbro improve smoothness and performance?

Hi,
iirc, these carbs are just cheap copies of mikuni's.
the alloy seems to be quite soft on them & they nearly always run rich.
but if its set up correctly & running ok, why bother changing it?
though if your set on replacing the cheap chinese parts with quality parts, then the mikuni is ideal.
xian racing do straight swap over kits.
in combination with an open air filter & the right main jet, you may even get an extra 5mph.
cheers,
GAZ

thanks gaz for your reply.

i have been talking to other people and according to them they say it would make a big improvement if chasing the carb to, indeed a mikuni or a keihin one.

for me power is not the most important...this bike is ment for cruising...but it can be a whole lot smoother.

now my second question is; which type mikuni or keihin carb can i put in my bike. the engine is a copy of a honda gc125 and i don't know which carbs they had.

an old hayes manual says something about a keihin pd88e but so far as i know those are not made anymore.
